Objectives: Hearing loss (HL) is regarded as a major risk factor for late-life depression. This study aims to further examine the association between HL and suicidal ideation (SI) among middle-aged and older adults using a nationally representative sample.
Method: The study sample comprised 34,142 adults (aged 50+) drawn from the 2015 to 2018 National Survey on Drug Use and Health. SI was measured by response to the question, 'At any time in the past year, did you seriously think about trying to kill yourself?' HL was assessed by asking respondents whether they were deaf or had serious difficulty hearing. Multivariate logistic regression analyses were conducted to examine the association between HL and SI after adjusting for a comprehensive list of covariates.
Results: Compared to those without HL, middle-aged and older adults with HL experienced significant health disparities regarding history of hospitalization, poor perceived health, higher prevalence of chronic diseases, depression, substance use, and SI. HL was positively associated with SI in the past year in both middle-aged (aOR = 1.59, 95% CI [1.14, 2.21], p < .001) and older adult groups (aOR = 1.58, 95% CI [1.07, 2.33], p < .001), controlling for depression, substance use, health status, and sociodemographic variables.
Conclusion: Given the high prevalence of hearing loss (HL) in aging populations, this study aimed to expand our knowledge of the relative strength of association between HL and SI. Findings implied that healthcare providers should consider screening for SI in those with HL.
